Antibiotic Dosing in Multiple Organ Dysfunction Syndrome
Chest, 2011Although early and appropriate antibiotic therapy remains the cornerstone of success for the treatment of septic shock, few data exist to guide antibiotic dose optimization in critically ill patients, particularly those with multiple organ dysfunction syndrome (MODS).

From the Entrance Dose to the Calculation of Organ Doses
Radiation Protection Dosimetry, 1998The dose-area product (DAP) as well as the dose at a reference point are accepted as standard measures for the risk from radiation exposure. A special ionisation chamber (Diamentor M4-KDK, PTW) enables both kinds of measurements at the same time. A software for the calculation of organ doses based on conversion factors published by NRPB is presented ...

Comparison of head and body organ doses in CT
Physics in Medicine and Biology, 2007We compare head and body organ doses received by adult patients undergoing whole body scans operated using the same technique factors. Dosimetry data were obtained for six CT scanners (16 and 64 slice) from four vendors. Organ doses were obtained using the ImPACT CT dose software package for an adult male, together with the corresponding head and body ...

Doses to critical organs from dental radiography
Oral Surgery, Oral Medicine, Oral Pathology, 1976Participants in the jointly sponsored Atomic Bomb Casualty Commission and Japanese National Institute of Health (ABCC-JNIH) Adult Health Study, a fixed-population sample under continual observation for late effects of the atomic bombs, are also being evaluated for their exposure to other sources of ionizing radiation. In the present study, the subjects'

[Determination of organ doses and effective doses in radiooncology].
Strahlentherapie und Onkologie : Organ der Deutschen Rontgengesellschaft ... [et al], 2008With an increasing chance of success in radiooncology, it is necessary to estimate the risk from radiation scatter to areas outside the target volume. The cancer risk from a radiation treatment can be estimated from the organ doses, allowing a somewhat limited effective dose to be estimated and compared.The doses of the radiation-sensitive organs ...

Scan region and organ doses in computed tomography
Radiation Protection Dosimetry, 2011The purpose of this study was to investigate how the choice of the scanned region affects organ doses in CT. ImPACT CT Patient Dosimetry Calculator (version 1.0) was used to compute absorbed doses to eight organs of interest in medical radiation dosimetry. For 13 dosimetry data sets, the authors calculated the maximum organ dose (D(max)) as well as the

Normalized Organ Doses in Tables
2019In this section, tables of normalized organ doses for conventional radiographs are listed that have been published thus far to the knowledge of the authors. The literature listings comprise tables and single publications to normalized organ doses in conventional radiology (Tables 29.1, 29.2, 29.3 and 29.4).

Weighting of secondary radiations in organ dose calculations
Radiation Protection Dosimetry, 2010The current system of dose quantities in radiological protection is based, in addition to the absorbed dose, on the concepts of equivalent dose and effective dose. This system has been developed mainly with uniform whole-body exposures in mind. Conceptual and practical problems arise when the system is applied to more general exposure situations where ...

Exposure and organ dose estimation in diagnostic radiology
Medical Physics, 1986This paper discusses a methodology which uses a specially developed computer program that enables estimation of output parameters of an x‐ray machine from a single test exposure. Exposure at skin entrance values can be estimated, as well as using the data from the program for organ dose estimates.

THEORETICAL ORGANICALLY BOUND TRITIUM DOSE ESTIMATES
Health Physics, 2004This paper illustrates a theoretical approach to estimating the dose associated with the ingestion of both organically bound tritium and tissue free water tritium relative to the ingestion of only tissue free water tritium. Organically bound tritium, specifically non-exchangeable OBT, can result in an increased dose relative to that from exchangeable ...
